In a textbook I am looking to place a large left margin at every page of
each chapter. At left printed pages a left margin and at right printed
pages a right margin, so like a double sided construction. In this
margin I would like to place:
You can use a custom layout with a narrow text block and a wide
rightmargin area.
1. Keywords and small descriptions to emphasize some text from the textflow
Use the \inright etc. commands or create your own commands based on
\inright, look at the margindata mechanism for more information.
2. Figures
You can change the default location of figures from the text block to
the margin area.
3. An expansion of a table that is placed in the main textflow but that
needs to cover a wider range then the text area so it expands into the
margin
In the example below I added a check to the table float to either center
the small tables or align wide tables on the inner margin which extend
into the margin area. While this method works in a simple example for a
real document I suggest to create a clone of the table float (e.g.
widetable) because the method in the example can lead to
problems/limitations.
What is the the easiest way to achieve this?
%%%% begin example
\setuppagenumbering
[alternative=doublesided]
\setuplayout
[width=10cm,
rightmargin=6cm]
\showframe
\def\FloatTableALignment
{\dowithnextbox
{\ifdim\nextboxwd>\textwidth
\doalignedline{inner}{\flushnextbox}%
\else
\flushnextbox
\fi}
\hbox}
\setupfloat[table][command=\FloatTableALignment]
\setupfloat[figure][default=rightmargin]
\starttext
\inright{Lorem ipsum \unknown}\samplefile{lorem}
\startplacefigure
\externalfigure[dummy][width=\rightmarginwidth]
\stopplacefigure
\samplefile{lorem}
\startplacetable
\bTABLE
\bTR
\bTD one \eTD
\bTD two \eTD
\bTD three \eTD
\eTR
\eTABLE
\stopplacetable
\samplefile{lorem}
\startplacetable
\bTABLE[textwidth=\dimexpr\textwidth+\rightmarginwidth+\rightmargindistance\relax,option=stretch]
\bTR
\bTD one \eTD
\bTD two \eTD
\bTD three \eTD
\eTR
\eTABLE
\stopplacetable
\samplefile{lorem}
\stoptext
%%% end example
